In an interview in the September 2011 edition of Metro You magazine, Rhonda Walker talked about the pain she felt during her divorce. There is no news of a subsequent marriage, so as far as anyone outside of her family knows, Ms. Walker is still a divorcée as of 2015.
A PDF copy of the article is available through the website of the Rhoda Walker Foundation. Few other reliable sources of information about Ms. Walker's divorce exist online, as she prefers interviews and similar matters to focus on her work and achievements rather than her marital status. Her ex-husband's Wikipedia entry also mentions the divorce, but it does not contain any details or dates.
